1939, Serial No. 260542 (Granted under the act of March 3, 1883, as

amended April 30,

The inventicn described heroin may be manufactured and used by or forthe Government of the United States for governmental purposes withoutthe paynent to me of any royalty thereon in accordance with the provisions of the act of Aprl 30, 1928 (Ch. 460, 45 Stat. L. 467).

This invention relates to waterproofing masonry walls, but moreparticularly the brick walls of buildings, and the invention has for itsobject to provide simple, cheap and durable "stenciling hawks", by meansof which the waterproofing rout may be quickly applied to the mortarjoints of a brick wall in a highly efficient, effective and economicalmanner, so that upon completion of the waterprocfing operation, the wallis left with an improved smooth and finished appearance and without thenecessity of any cleaning or removal of excess grouting materialtherefrom.

With this object in View, the invention consists of the novelconstruction and arrangement of the stenciling hawks, which forconvenience of operation and most satisfactory results, should be usedin pairs in the manner of and for the purposes hereinafter described.

Referring to the accompanying drawings:

Fig. 1 is a plan View of one of the pair of stenciling hawks used in theoperation of waterprooing the horizontal joints between the courses of abrick wall.

Fig, 2 is a vertical sectional View through the same.

Fig. 3 is a plan View of the other one of the pair of stenciling hawksused in the operation of waterproofing the vertical joints between thebricks.

Fig. 4 is a Vertical sectional view through the same.

Fig. 5 is a plan View illustrating the application to brick wall of thestenciling hawk shown in Fig. 1, and

Fig. 6 is a similar View showing the application to a brick wall of thestenciling hawk shown in Fle. 3.

Like numerals of reference indicate the same parts throughout theseveral figures, in which:

l indicates the stenciling hawk shown in Fig. 1 which I will designateas the horizontal hawk and 2 indicates the stenciling hawk shown in Fig.3, which I will designate as the vertical hawk.

On each of the stenciling hawks l and 2 there Extending upwardly fromthis trough 3, and preferably integral therewith is a fiat metallicback-member 4. suitable ends 5 are provided for the troughs 3, and Iprefer to provide a suitable bead at each of the vertical edges of thehawks 5 for the purpose of stiffening the structures.

In the horizontal hawk l (Fig. l) there is pro- Vided a longitudlnalhorizontal open slot 'l in the flat back-member 4 which slot extendsthrough nearly the entire width of the back-member 4; that portion ofthe material at the ends of the slot l being provided with a rear-wayextending bead or crimp 8.

Arrangecl on the front and rear sides of the back-member 4 and along thehorizontal edges OI" the slot 'l are two fiexible rubber strips 9, theedge portions of which slightly overlap the top and bottom edges of theslot l, as shown in dotted lines in Fig. 1.

The vertical stenciling hawk 2 (Fig. 3) is provided in its back-member4, with two horizontal rearwardly extending heads or crimps te and Il,spaced apart a distance equal to that of the mortar joints between twoCourses of brick, while centrally of the back-member is an oblongopening I 2 which extends from the center line of the upper bead orcrimp lil to the center line of the lower bead or crimp l i. SuitablySecured to the rear surface of the back-member 4 is a small fiexiblerubber sheet !3 having a vertical slot M provided therein, theedge-portons of which sheet acljacent its slot !4 overlap the verticaledges l of the oblong opening z in the metallic back-member 4.

The widths of the horizontal opening between the two rubber strips inFig. 1, and of the slot in the rubber sheet !3 in Fig. 3 is equal to thewidths of the horizontal and vertical mortar joints between the bricks,while each of the stenciling hawks is provided centrally of theirtroughs 3 with a depending handle !5, for convenient support and correctpositioning of the hawks by the hand of the artisan using them.

Having thus described the Construction of the stenciling hawks, themanner in which they are 45 used in the application of waterproofinggrout to the joints of brick walls is as follows:

A quantity of suitable waterproofing grout is placed in the trough 3 ofthe stenciling hawk l, and the hawk is placed against the surface of 50the wall ll, as shown in Fig. 5, so that the beads or crimps 3 thereinregister in the horizontal mortar joint !8 of the wall. This aligns thehorizontal slot 'l of the hawk with the horizontal mortar joint so thatthe entire joint within the 55 length of the slot 7 is exposed, but thecontiguous surfaces of the bricks are covered by the backmember of thehawk. When in this position, grout contained in the trough 3 is brushedinto the mortar joint which is exposed through the slot l. By reason ofthe flexible rubber pieces 9 at the top and bottom edges of the slot 1,a close contact is preserved at the adjacent edges of the brickssufiicient to prevent the grout from running down behind the back-memberof the hawk and over the surface of the bricks. By this construction thesurplus grout from the stiff brush s caused to run down the outer faceof the backmember and into the grout trough 3, thus conserving the groutand obviating all waste. The hawk is moved along the horizontal joint asfast as the grout can be brushed in.

When using the vertical hawk 2, it is similarly placed against the wallsurface so that the two horizontal beads or crimps o and II thereofregister with two horizontal mortar joints !8, and the vertical slot Mthereof uncovers a vertical mortar joint between two bricks. The groutis then similarly applied with a stiff brush and brushed into the joint.Similarly the flexible rubberin which the vertical slot !4 is formedprovides a close contact With the adjacent faces of the bricks sufcientto prevent the grout from running down behind the hawk and over thesurface of the bricks. Likewise the surplus grout from the stiff brushis caused to run down the outer face of the hawk and into the grouttrough. The hawk is moved from joint to joint in order to complete theapplication of the grout to the vertical joints in the wall.

Having thus fully described the use of the stenciling hawks in theapplication of waterproofing grout to the horizontal and vertical mortarjoints of a wall, I do not wish to be understood as confirming myself tothe exact Construction of the hawks as illustrated in the drawings anddescribed herein, since such illustration and description is onlyintended to disclose what I consider to be an example of a simple andsatisfactory Construction. Various changes, alerations and modificationsmay be made in the Construction and arrangements of the parts withoutdeparting from the spirit of the invention, and I consider myselfclearly entitled to all of such as fall within the limit and scope ofthe appended claims.
